The one adult in the building everyone pretends not to fear.

means The person with overall responsibility for running a school — academically, administratively, and for pretty much everything that goes wrong.

from A plain compound of 'head' (meaning chief or foremost, as in headmaster, head chef) plus 'teacher.' British English favors 'headteacher' or 'head,' gender-neutral by design, replacing the older split of 'headmaster' and 'headmistress' as schools moved toward a single unisex title.
